About: 61 Cancri

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

61 Cancri (61 Cnc) is the Flamsteed designation for a visual binary star system in the northern constellation Cancer. The pair have a combined apparent magnitude of 6.25, which means 61 Cancri is faintly visible to the naked eye. (According to the Bortle scale, it can be seen from rural or even dark suburban skies.) Based upon parallax measurements, the system is approximately 181 light years away from Earth.

  • 61 Cancri (61 Cnc) is the Flamsteed designation for a visual binary star system in the northern constellation Cancer. The pair have a combined apparent magnitude of 6.25, which means 61 Cancri is faintly visible to the naked eye. (According to the Bortle scale, it can be seen from rural or even dark suburban skies.) Based upon parallax measurements, the system is approximately 181 light years away from Earth. The two components appear to be roughly identical with individual masses of about 1.4 times that of the Sun and apparent magnitudes of 7.0. Their combined stellar classification is F4V, matching that of an F-type main sequence star. They have an angular separation of 0.300″ along a position angle of 129.0° (as of 2014). The pair orbit each other with an estimated period of 40.657 years. No significant level of chromospheric activity has been detected coming from either star. (en)
  • 61 Cancri è una stella bianco-gialla nella sequenza principale di magnitudine 6,25 situata nella costellazione del Cancro. Dista 164 anni luce dal sistema solare. (it)
  • 61 Cancri, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna, belägen i den norra delen av stjärnbilden Kräftan. Den har en kombinerad skenbar magnitud av ca 6,29 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 18,0 mas, beräknas den befinna sig på ett avstånd på ca 181 ljusår (ca 56 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 10 km/s. (sv)
